Scanmatik OBD to JCB 9pin need pinout

[notsku]

I have JCB with 9pin connector A, B , H and J connected. Which one is right OBD3-H OBD11-J OR OBD6-H OBD14-J ?

I think there has to be other 9 pin port with C and D connected or this one has 2 wires not connected. So for J1939 obd6 to C, obd14 D, obd 4&5 to A and obd16 to B.
